Therefore, the profile curve lengthwithin the effective half diameter of any surface of any lens has to becontrolled. The ratio between the profile curve length (ARS) within theeffective half diameter of one surface and the thickness (TP) of thelens, which the surface belonged to, on the optical axis (i.e., ARS/TP)has to be particularly controlled.

Forany surface of other lenses in the optical image capturing system, theratio between the profile curve length of the maximum effective halfdiameter thereof and the thickness of the lens which the surfacebelonged to is denoted in the same manner.

For any surface of any lens, the profile curve length within a half ofthe entrance pupil diameter (HEP) affects the ability of the surface tocorrect aberration and differences between optical paths of light indifferent fields of view. With longer profile curve length, the abilityof correcting aberration is better. However, the difficulty ofmanufacturing increases as well. Therefore, the profile curve lengthwithin a half of the entrance pupil diameter (HEP) of any surface of anylens has to be controlled. The ratio between the profile curve length(ARE) within a half of the entrance pupil diameter (HEP) of one surfaceand the thickness (TP) of the lens, which the surface belonged to, onthe optical axis (i.e., ARE/TP) has to be particularly controlled.

In an embodiment, when the lenses satisfy f2|+|f3|+|f4| and |f1|+|f5|,at least one lens among the second to the fourth lenses could have weakpositive refractive power or weak negative refractive power. Herein theweak refractive power means the absolute value of the focal length ofone specific lens is greater than 10. When at least one lens among thesecond to the fourth lenses has weak positive refractive power, it mayshare the positive refractive power of the first lens, and on thecontrary, when at least one lens among the second to the fourth lenseshas weak negative refractive power, it may finely correct the aberrationof the system.

In an embodiment, the fifth lens could have negative refractive power,and an image-side surface thereof is concave, it may reduce back focallength and size.

Second Embodiment

As shown in FIG. 2A and FIG. 2B, an optical image capturing system 20 ofthe second embodiment of the present invention includes, along anoptical axis from an object side to an image side, an aperture 200, afirst lens 210, a second lens 220, a third lens 230, a fourth lens 240,a fifth lens 250, an infrared rays filter 280, an image plane 290, andan image sensor 292. FIG. 2C is a transverse aberration diagram at 0.7field of view of the second embodiment of the present application.

The first lens 210 has positive refractive power, and is made ofplastic. An object-side surface 212 thereof, which faces the objectside, is a convex aspheric surface, and an image-side surface 214thereof, which faces the image side, is a concave aspheric surface.

The second lens 220 has negative refractive power, and is made ofplastic. An object-side surface 222 thereof, which faces the objectside, is a concave aspheric surface, and an image-side surface 224thereof, which faces the image side, is a concave aspheric surface. Theobject-side surface 222 and the image-side surface 224 both have aninflection point.

The third lens 230 has positive refractive power, and is made ofplastic. An object-side surface 232, which faces the object side, is aconvex aspheric surface, and an image-side surface 234, which faces theimage side, is a concave aspheric surface. The object-side surface 232has an inflection point, and the image-side surface 234 has twoinflection points.

The fourth lens 240 has positive refractive power, and is made ofplastic. An object-side surface 242, which faces the object side, is aconcave aspheric surface, and an image-side surface 244, which faces theimage side, is a convex aspheric surface. The object-side surface 242has three inflection points, and the image-side surface 244 has aninflection point.

The fifth lens 250 has negative refractive power, and is made ofplastic. An object-side surface 252, which faces the object side, is aconvex surface, and an image-side surface 254, which faces the imageside, is a concave surface. It may help to shorten the back focal lengthto keep small in size. In addition, the object-side surface 252 and theimage-side surface 254 both have an inflection point, which may reducean incident angle of the light of an off-axis field of view and correctthe aberration of the off-axis field of view.

The infrared rays filter 280 is made of glass, and between the fifthlens 250 and the image plane 290. The infrared rays filter 280 gives nocontribution to the focal length of the system.

The optical image capturing system of the second embodiment satisfies|f2|+|f3|+|f4|=113.1345 mm; |f1|+|f5|=10.0209 mm; and|f2|+|f3|+|f4|>|f1|+|f5|, where f2 is a focal length of the second lens220, f3 is a focal length of the third lens 230, f4 is a focal length ofthe fourth lens 240, and f5 is a focal length of the fifth lens 250.

In the second embodiment, the first lens 210, the third lens 230, andthe fourth lens 240 are positive lenses, and their focal lengths are f1,f3, and f4. The optical image capturing system of the second embodimentfurther satisfies ΣPP=f1+f3+f4=108.48285 mm; and f1/(f1+f4+f5)=0.05129,where ΣPP is a sum of the focal lengths of each positive lens. It ishelpful to share the positive refractive power of the first lens 210 toother positive lenses to avoid the significant aberration caused by theincident rays.

The optical image capturing system of the second embodiment furthersatisfies ΣNP=f2+f5=−14.67262 mm; and f5/(f2+f5)=0.30376, where f2 is afocal length of the second lens 220, f5 is a focal length of the fifthlens 250, and ΣNP is a sum of the focal lengths of each negative lens.It is helpful to share the negative refractive power of the fifth lens250 to the other negative lens.

Fifth Embodiment

As shown in FIG. 5A and FIG. 5B, an optical image capturing system ofthe fifth embodiment of the present invention includes, along an opticalaxis from an object side to an image side, an aperture 500, a first lens510, a second lens 520, a third lens 530, a fourth lens 540, a fifthlens 550, an infrared rays filter 580, an image plane 590, and an imagesensor 592. FIG. 5C is a transverse aberration diagram at 0.7 field ofview of the fifth embodiment of the present application.

The first lens 510 has positive refractive power, and is made ofplastic. An object-side surface 512, which faces the object side, is aconvex aspheric surface, and an image-side surface 514, which faces theimage side, is a concave aspheric surface.

The second lens 520 has negative refractive power, and is made ofplastic. An object-side surface 522 thereof, which faces the objectside, is a convex aspheric surface, and an image-side surface 524thereof, which faces the image side, is a concave aspheric surface. Theimage-side surface 524 has an inflection point.

The third lens 530 has positive refractive power, and is made ofplastic. An object-side surface 532, which faces the object side, is aconvex aspheric surface, and an image-side surface 534, which faces theimage side, is a concave aspheric surface. The object-side surface 532has an inflection point, and the image-side surface 534 has twoinflection points thereon.

The fourth lens 540 has positive refractive power, and is made ofplastic. An object-side surface 542, which faces the object side, is aconcave aspheric surface, and an image-side surface 544, which faces theimage side, is a convex aspheric surface. The object-side surface 542has two inflection points.

The fifth lens 550 has negative refractive power, and is made ofplastic. An object-side surface 552, which faces the object side, is aconvex surface, and an image-side surface 554, which faces the imageside, is a concave surface. It may help to shorten the back focal lengthto keep small in size. In addition, the object-side surface 552 and theimage-side surface 554 both have an inflection point, which may reducean incident angle of the light of an off-axis field of view and correctthe aberration of the off-axis field of view.

The infrared rays filter 580 is made of glass, and between the fifthlens 550 and the image plane 590. The infrared rays filter 580 gives nocontribution to the focal length of the system.

The optical image capturing system of the second embodiment satisfies|f2|+|f3|+|f4|=112.4164 mm; |f1|+|f5|=7.2331 mm; and|f2|+|f3|+|f4|>|f1|+|f5|, where f2 is a focal length of the second lens520, f3 is a focal length of the third lens 530, f4 is a focal length ofthe fourth lens 540, and f5 is a focal length of the fifth lens 550.

In the fifth embodiment, the first lens 510, the third lens 530, and thefourth lenses 540 are positive lenses, and their focal lengths are f1,f3, and f4. The optical image capturing system of the fifth embodimentfurther satisfies PP=f1+f3+f4=106.69481 mm; and f1/(f1+f3+f4)=0.04159,where ΣPP is a sum of the focal lengths of each positive lens. It ishelpful to share the positive refractive power of the first lens 510 toother positive lenses to avoid the significant aberration caused by theincident rays.

The optical image capturing system of the fifth embodiment furthersatisfies ΣNP=f2+f5=−12.95472, and f5/(f2+f5)=0.21582, where f2 is afocal length of the second lens 520, f5 is a focal length of the fifthlens 550, and ΣNP is a sum of the focal lengths of each negative lens.It is helpful to share the negative refractive power of the fifth lens550 to the other negative lens.

Sixth Embodiment

As shown in FIG. 6A and FIG. 6B, an optical image capturing system ofthe sixth embodiment of the present invention includes, along an opticalaxis from an object side to an image side, an aperture 600, a first lens610, a second lens 620, a third lens 630, a fourth lens 640, a fifthlens 650, an infrared rays filter 680, an image plane 690, and an imagesensor 692. FIG. 6C is a transverse aberration diagram at 0.7 field ofview of the sixth embodiment of the present application.

The first lens 610 has positive refractive power, and is made ofplastic. An object-side surface 612, which faces the object side, is aconvex aspheric surface, and an image-side surface 614, which faces theimage side, is a concave aspheric surface. The object-side surface 612and the image-side surface 614 both have an inflection point.

The second lens 620 has negative refractive power, and is made ofplastic. An object-side surface 622 thereof, which faces the objectside, is a convex aspheric surface, and an image-side surface 624thereof, which faces the image side, is a concave aspheric surface. Theobject-side surface 622 and the image-side surface 624 respectively havean inflection point.

The third lens 630 has positive refractive power, and is made ofplastic. An object-side surface 632, which faces the object side, is aconvex aspheric surface, and an image-side surface 634, which faces theimage side, is a convex aspheric surface. The object-side surface 632has an inflection point.

The fourth lens 640 has positive refractive power, and is made ofplastic. An object-side surface 642, which faces the object side, is aconcave aspheric surface, and an image-side surface 644, which faces theimage side, is a convex aspheric surface. The object-side surface 642and the image-side surface both have an inflection point.

The fifth lens 650 has negative refractive power, and is made ofplastic. An object-side surface 652, which faces the object side, is aconvex surface, and an image-side surface 654, which faces the imageside, is a concave surface. The object-side surface 652 and theimage-side surface 654 both have an inflection point. It may help toshorten the back focal length to keep small in size. In addition, it mayreduce an incident angle of the light of an off-axis field of view andcorrect the aberration of the off-axis field of view.

The infrared rays filter 680 is made of glass, and between the fifthlens 650 and the image plane 690. The infrared rays filter 680 gives nocontribution to the focal length of the system.

The optical image capturing system of the second embodiment satisfies|f2|+|f3|+|f4|=26.1024 mm; |f1|+|f5|=10.9792 mm; and|f2|+|f3|+|f4|>|f1|+|f5|, where f2 is a focal length of the second lens620, f3 is a focal length of the third lens 630, f4 is a focal length ofthe fourth lens 640, and f5 is a focal length of the fifth lens 650.

In the sixth embodiment, the first lens 610, the third lens 630, and thefourth lenses 640 are positive lenses, and their focal lengths are f1,f3, and f4. The optical image capturing system of the sixth embodimentfurther satisfies ΣPP=f1+f3+f4=21.25779 mm; and f1/(f1+f3+f4)=0.35286,where f1 is a focal length of the first lens 610, f3 is a focal lengthof the third lens 630, f4 is a focal length of the fourth lens 640, andΣPP is a sum of the focal lengths of each positive lens. It is helpfulto share the positive refractive power of the first lens 610 to otherpositive lenses to avoid the significant aberration caused by theincident rays.

The optical image capturing system of the sixth embodiment furthersatisfies ΣNP=f2+f5=−15.82380 mm; and f5/(f2+f5)=0.21980, where f2 is afocal length of the second lens 620, f5 is a focal length of the fifthlens 650, and ΣNP is a sum of the focal lengths of each negative lens.It is helpful to share the negative refractive power of the fifth lens650 to the other negative lens to avoid the significant aberrationcaused by the incident rays.
